[edk2-devel] question about qemu+kvm+ovmf+winxp

[Junhao Gao]

Hi David 

	I have found this compiled OVMF-with-csm.fd can support winxp booting up.
	OVMF-with-csm.fd path: https://www.kraxel.org/repos/jenkins/seabios/seabios.git-csm-1.12.0-33.63.g43f5df7.x86_64.rpm
	Then could you help to provide me the compile method and base code to reproduce this OVMF-with-csm.fd?

Thanks,
Junhao

Hi Laszlo
	Thank you very much for your great support.

Hi David
	Refer to http://www.linux-kvm.org/downloads/lersek/ovmf-whitepaper-c770f8c.txt.

	Interested users and developers should look for OVMF's "-D CSM_ENABLE"
	build-time option, and check out the <https://www.kraxel.org/repos/> continuous
	integration repository, which provides CSM-enabled OVMF builds.
	
	Could you help me to choose which branch supporting CSM, and more details, thanks very much.

Thanks,
Junhao

To my understanding, the first Windows "family" with any kind of UEFI support is Windows 7.

OvmfPkg/README has some comments on Windows support:

If you'd like to virtualize Windows XP on QEMU/KVM, please use SeaBIOS for guest firmware.

You can also try to build OVMF with -D CSM_ENABLE, but for that, you'll have to build SeaBIOS in CSM mode first, and embed that binary into OVMF at build time. Please ask David for details (CC'd).

Thanks
Laszlo
